Abstract: According to the performance test requirements of the solution air conditioning unit and the climate characteristics of Fuzhou,the indoor and outdoor simulation test platform is designed and built.The test platform in the annual climate,the outdoor simulation room can be achieved wet and dry bulb temperature from 35 ℃、 28 ℃ to-7℃、-8℃ changes.The temperature of the wet and dry bulb in the indoor simulation room can be changed between 27℃、19℃ to 20℃、13.5℃.In order to reduce the energy consumption of the test platform,various test conditions for different climate situation in Fuzhou area were analyzed.Get the test platform for winter heat recovery and summer cooling recovery program,the use of solution air conditioning as a cold and hear source and the air parameters for processing.The results show that the design takes full account of the cold and heat recovery,reduce the equipment capacity so as to reduce the initial investment,reduce the hot and cold load and thus reduce the operating costs,achieve a lower cost on the indoor and outdoor climate simulation test.
